The Chateau Marmont exhibition will feature 25 bongs by about 30 artists, with prices ranging from $5,000 to $300,000.

Call it high art. A pop-up art gallery inside the Chateau Marmont hotel features a display of hand-blown, art-glass marijuana paraphernalia — and the price tags run into the hundreds of thousands of dollars.

Grey Space Art, which will be at the hotel through Oct. 5, is the brainchild of a 22-year-old New Yorker named Benjamin Milstein, who said he amassed cash after investing in cannabis stock in 2013 two weeks before it became legal in Colorado.

That sparked an interest in functional glass art in the form of bongs and pipes and prompted him to embark on a journey around the world — Japan, the Netherlands, Britain and Spain, among other places — to buy sculptural works.
